Do you know that one out of three apparel purchases made online is returned? Imagine if one out of every three restaurant customers sent their food back, or one out of three travelers canceled their flight tickets. Well, the 33% return rate would be untenable!

As an E-commerce retailer, you might understand that online business is a different beast from brick-and-mortar, especially when it comes to apparel. Online customers are unable to try on items, figure out the right size, touch, and feel the product, and only have a limited ability to see intricate details. That’s why fit and sizing top the list of reasons that consumers make returns.

By integrating apps and tools to help shoppers make smarter fit decisions, online retailers can dramatically reduce their return rates. But which size chart apps should you choose? There are multiple clothing size chart generator apps around, varying in features, costs, level of customization, and other elements.
